Monnie Price Jr., known on stage as Lil Monnie23, was shot and killed on Interstate 580 in Oakland, California, on October 27, 2021. The shooting happened during the evening rush near the 98th Avenue on-ramp. Price was driving a white Chevrolet sedan and was struck by fire from a .223-style rifle; rifle casings were recovered at the scene. He was able to keep driving until the MacArthur Boulevard off-ramp, where he succumbed to his wounds.

Investigators described the attack as an ambush that stemmed from an escalating feud between Price and another local rapper, Larry Coney, with both artists having released music aimed at each other. On the day of the shooting, Coney, driving a gold Mercedes, is reported to have pursued and ambushed Price on the freeway; the CHP said the attack had been planned for weeks and that the motive included a desire for notoriety. The Price family lost a second son to gun violence in this incident.

If anyone witnessed the pursuit or the shooting on I-580 that evening, or has information about the feud and movements of either vehicle, please come forward.
